Apply after Foundation and before Secret Concealer to the under eye area. Using the Secret Camouflage Brush, lightly pick up a tiny amount of Under Eye Perfector. Using feather-light strokes, gently apply to the dark area under the eye. Apply sheerly and layer for more coverage where necessary. Using your ring fingertip, gently tap the product seamlessly into the skin. Apply Secret Concealer over the area where you applied Under Eye Perfector and set with Secret Brightening Powder with the Camouflage Powder Brush.
